Opel/Vauxhall will unveil a coupe concept at the Geneva auto show that will point to its future design language.
The car will be badged GT in recognition of the iconic Opel GT, a successful subcompact coupe built between 1968 and 1973. The Geneva concept is expected to be a similar size.
Opel said in a statement that the GT Concept will be a "breathtaking and puristic sportscar" that expresses the continuous innovative strength and the new lifestyle of Opel.
The design language will be an evolution of the 'sculptural artistry meets German precision' look first seen on the Opel Insignia midsize car launched in 2008 and updated for the Monza coupe concept unveiled at the 2013 Frankfurt auto show, a spokesman said.
The Monza was designed by Opel's current head of design, Mark Adams.
Elements of the Monza have appeared on new cars, for example in the sharper body creases of the new Astra compact, the spokesman said.
